Ingredients

• 10 large eggs

• 1 cup milk (whole or 2%)

• 1 ½ cups shredded cheddar cheese

• 1 cup shredded Monterey Jack cheese

• 1 medium onion, diced

• 1 red bell pepper, diced

• 1 green bell pepper, diced

• 1 cup black beans, drained and rinsed

• 1 cup corn kernels (fresh, frozen, or canned)

• 1 medium tomato, diced

• 1 small jalapeño, finely chopped (optional for heat)

• 2 cups cooked diced potatoes or hash browns

• 1 teaspoon chili powder

• 1 teaspoon ground cumin

• ½ teaspoon smoked paprika

• ½ teaspoon garlic powder

• Salt and black pepper, to taste

• 2 tablespoons olive oil

• ¼ cup fresh cilantro, chopped (plus more for garnish)

• Sour cream or avocado slices, for serving (optional)

Directions

1. Preheat and Prepare the Dish
   Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or nonstick spray.

2. Sauté the Vegetables
   In a large skillet, heat olive oil over medium heat. Add the diced onion, red and green bell peppers, and jalapeño if using. Cook for 4–5 minutes until softened. Add corn, black beans, and diced tomato. Stir in chili powder, cumin, smoked paprika, and garlic powder. Season with salt and pepper, then cook for another 2 minutes. Remove from heat and set aside.

3. Whisk the Eggs
   In a large mixing bowl, whisk together eggs and milk until smooth. Stir in half of the cheddar and Monterey Jack cheeses, along with the chopped cilantro.

4. Assemble the Casserole
   Spread the cooked potatoes or hash browns evenly in the prepared baking dish. Top with the sautéed vegetable mixture, spreading it out evenly. Pour the egg mixture over the top, ensuring it covers all ingredients. Gently shake the dish to allow the eggs to settle evenly.

5. Add the Cheese Layer
   Sprinkle the remaining cheddar and Monterey Jack cheeses on top for that perfect golden crust.

6. Bake the Casserole
   Place the dish in the preheated oven and bake for 35–40 minutes, or until the center is set and the top is lightly golden brown. To check doneness, insert a knife into the center—it should come out clean.

7. Cool and Garnish
   Let the casserole cool for about 10 minutes before slicing. Garnish with extra cilantro, diced avocado, or a dollop of sour cream for an extra burst of flavor.

8. Serve and Enjoy
   Slice into generous portions and serve warm. Pair with a fresh fruit salad, a side of salsa, or crispy roasted potatoes for a complete breakfast spread.

5. Let It Rest: Allowing the casserole to cool before cutting ensures clean, firm slices.

Storage and Reheating Tips

This casserole stores beautifully, making it ideal for meal prep or leftovers.

• Refrigerate: Store leftovers in an airtight container for up to 4 days.

• Freeze: Wrap portions tightly in foil or plastic wrap and freeze for up to 2 months.

• Reheat: Warm individual servings in the microwave for 1–2 minutes or bake at 350°F (175°C) until heated through.

Pro tip: Add a sprinkle of fresh cheese before reheating to bring back that melty goodness!

Make-Ahead and Meal Prep Option

If you’re hosting brunch or preparing for a busy week, this casserole can easily be made in advance:

• Assemble Ahead: Prepare all ingredients, pour into the baking dish, and cover tightly with foil or plastic wrap. Refrigerate overnight.

This make-ahead convenience is what makes the Southwest Egg Casserole perfect for holidays, busy mornings, or weekend gatherings when you’d rather spend time with family than in the kitchen.

Variations to Try

Looking to give your casserole a personal twist? Here are a few fun variations:

Notes

• Always allow the casserole to cool slightly before cutting; this helps it set and makes serving easier.

• To feed a larger crowd, double the recipe and use two baking dishes.

• This recipe works great as a breakfast-for-dinner option—serve with a side salad or roasted vegetables.

Frequently Asked Questions

Can I use egg whites instead of whole eggs?
Yes, you can substitute some or all of the whole eggs with egg whites if you prefer a lighter version. Using just egg whites will reduce the fat and calories in the casserole while still providing plenty of protein. Keep in mind that the texture will be slightly less creamy compared to using whole eggs because the yolks add richness and help the casserole set more firmly. To maintain flavor, you can add a little extra cheese or a splash of milk or cream to the egg whites, which will give the dish a creamier consistency. This option works well for anyone looking to make the casserole a bit healthier without sacrificing too much taste.

Can I use frozen vegetables?
Absolutely! Frozen vegetables such as bell peppers, corn, or hash browns are convenient and work perfectly in this recipe. They save prep time and still deliver great flavor. The key is to thaw them fully and drain any excess moisture before adding them to the casserole. Excess water can make the casserole watery or prevent it from setting properly. If you’re short on fresh vegetables or want to prep ahead, frozen vegetables are a fantastic and reliable alternative that keeps the dish flavorful and colorful.

Can I prepare it the night before?
Yes, this casserole is perfect for make-ahead preparation. You can assemble it entirely the night before, cover it tightly with foil or plastic wrap, and refrigerate overnight. In the morning, simply bake it as directed. This makes it ideal for busy mornings, holiday brunches, or any occasion where you want a stress-free breakfast ready to go. Preparing it ahead also allows the flavors to meld overnight, enhancing the overall taste of the dish.

How can I make it spicier?
If you enjoy a bit of heat, you can easily adjust the spice level. Add extra jalapeños, diced green chiles, or a pinch of cayenne pepper to the vegetable mixture. You can also serve it with a drizzle of hot sauce on top after baking for a bold kick. Adjust the heat according to your family’s preference to make it just right.

This Flavor-Packed Southwest Egg Casserole isn’t just a breakfast dish—it’s a celebration of vibrant flavors, hearty ingredients, and simple preparation.
